@merge GCC 5.3.  round 1.  this probably won't work  :-)

libsanitizer likely needs to be re-ported, though i've done most of
the updating we'll need i think already.

@import GCC 4.8 branch at r206687.

highlights from: http://gcc.gnu.org/gcc-4.6/changes.html

   GCC now has stricter checks for invalid command-line options
   New -Wunused-but-set-variable and -Wunused-but-set-parameter
      warnings
   Many platforms have been obsoleted
   Link-time optimization improvements
   A new switch -fstack-usage has been added
   A new function attribute leaf was introduced
   A new warning, enabled by -Wdouble-promotion
   Support for selectively enabling and disabling warnings via
      #pragma GCC diagnostic has been added
   There is now experimental support for some features from the
      upcoming C1X revision of the ISO C standard
   Improved experimental support for the upcoming C++0x ISO C++
      standard
   G++ now issues clearer diagnostics in several cases
   Updates for ARM, x86, MIPS, PPC/PPC64, SPARC
   Darwin, FreeBSD, Solaris 2, MinGW and Cygwin now all support
      __float128 on 32-bit and 64-bit x86 targets. [*1]

highlights from: http://gcc.gnu.org/gcc-4.7/changes.html

   The -fconserve-space flag has been deprecated
   Support for a new parameter --param case-values-threshold=n
      was added
   Interprocedural and Link-time optimization improvements
   A new built-in, __builtin_assume_aligned, has been added
   A new warning option -Wunused-local-typedefs was added
   A new experimental command-line option -ftrack-macro-expansion
      was added
   Support for atomic operations specifying the C++11/C11 memory
      model has been added
   There is support for some more features from the C11 revision
      of the ISO C standard
   Improved experimental support for the new ISO C++ standard,
      C++11
   Updates for ARM, x86, MIPS, PPC/PPC64, SH, SPARC, TILE*
   A new option (-grecord-gcc-switches) was added

highlights from: http://gcc.gnu.org/gcc-4.8/changes.html

   GCC now uses C++ as its implementation language.  This means
      that to build GCC from sources, you will need a C++
      compiler that understands C++ 2003
   DWARF4 is now the default when generating DWARF debug
      information
   A new general optimization level, -Og, has been introduced
   A new option -ftree-partial-pre was added
   The option -fconserve-space has been removed
   The command-line options -fipa-struct-reorg and
      -fipa-matrix-reorg have been removed
   Interprocedural and Link-time optimization improvements
   AddressSanitizer, a fast memory error detector, has been
      added  [*2]
   A new -Wsizeof-pointer-memaccess warning has been added
   G++ now supports a -std=c++1y option for experimentation
      with features proposed for the next revision of the
      standard, expected around 2014
   Improved experimental support for the new ISO C++ standard,
      C++11
   A new port has been added to support AArch64
   Updates for ARM, x86, MIPS, PPC/PPC64, SH, SPARC, TILE*


[*1] we should support this too!
[*2] we should look into this.
